Did I get the wrong valve stem seals?
I took a valve stem seal off to find that it has the seal and spring base all in one piece. The replacement seals are a set of COMP 511-16 seals that do not have a spring seat.
Can I just pop these seals on with a 13mm socket and let the spring rest on the head or do I need a new spring base?
Thanks in advance.

You have to have a base plate or the spring height will not be correct. Most spring sets come with the retainers and together they obtain the correct spring pressure. The stock springs were designed to work with the stock seals with the base plate.

I'm putting in the gm performance blue springs. I assume they should work with the stock base seals?

It was around that time frame. There were some motor internal component changes in late 2001, the valve seals might have been one of them. Don't put the springs right on the head, it will not only have too low a seat force but it will eat right through the aluminum.
Get the one piece GM seals or you need the earlier valve seats from GM. Either way what you currently have won't work.
